Hello Kitty is one of Japan’s most popular and beloved cartoon characters, and Tokyo’s landmark Keio Plaza Hotel celebrates Kitty in a big way, throughout its special themed rooms. The top hotel in Tokyo occupies two high-rise towers in the vibrant Shinjuku district, and features Kitty Town rooms created for kids and Princess Kitty rooms that are designed to please adult fans of the fictional cat. Definitely, over the top, there are bright pink bows of the room doors and Kitty paraphernalia everywhere, like the wallpaper, hairdryers, garbage cans, and even bathroom scales. Pink is splashed all over the place too, including pink tubs in the bathroom. Guests can even take home some of the room, like the Hello Kitty dolls that are on the beds, Hello Kitty water bottles, toiletry, and stationary. If you want to go, you’ll need to book about a year in advance, they’re that popular.
